Designation:A533/A533M16Used in USDOE-NE StandardsStandard Specification forPressure Vessel Plates,Alloy Steel,Quenched andTempered,Manganese-Molybdenum and Manganese-Molybdenum-Nickel1This standard is issued under the fixed designation A533/A533M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This specification2covers one type of manganese-molybdenum and four types of manganese-molybdenum-nickel alloy steel plates for use in the quenched and temperedcondition for the construction of welded pressure vessels.1.2 Material under this specification is available in fivetypes,designated“A”,“B”,“C”,“D”,and“E”.The material isalso available in three classes having the following strengthlevels.ClassTensile Strength,ksi MPa180100 550 to 690290115 620 to 7953100125 690 to 8601.3 The maximum thickness of Class 1 and Class 2 plates islimited only by the capacity of the composition to meet thespecified mechanical property requirements;however,currentpractice normally limits the maximum thickness to 12 in.300mm for Types A through D and to 7 in.180 mm for Type E.1.4 The maximum thickness of Class 3 plates is 212in.65mm for Types A through D and 2 in.50 mm for Type E.1.5 The minimum nominal thickness of plates of all classesis 0.25 in.6.5 mm.1.6 These alloy steel plates in the as-rolled condition aresensitive to cracking during transit and handling,particularly inthicknesses over about 1 or 2 in.25 or 50 mm.They shouldbe shipped in the as-rolled conditions only by mutual agree-ment of manufacturer and the purchaser.1.7 Plates covered by this specification are often used in thebeltline region of nuclear reactor vessels where the materialproperties may be affected by high levels of radiation.Appen-dix X1 provides some information pertinent to this usage.1.8 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard.Within the text,theSI units are shown in brackets.The values stated in eachsystem are not exact equivalents;therefore,each system mustbe used independently of the other.Combining values from thetwo systems may result in nonconformance with the specifi-cation.2.Referenced Documents2.1 ASTM Standards:3A20/A20M Specification for General Requirements for SteelPlates for Pressure VesselsA435/A435M Specification for Straight-Beam UltrasonicExamination of Steel PlatesA577/A577M Specification for Ultrasonic Angle-Beam Ex-amination of Steel PlatesA578/A578M Specification for Straight-Beam UltrasonicExamination of Rolled Steel Plates for Special Applica-tions3.General Requirements and Ordering Information3.1 Material supplied to this material specification shallconform to Specification A20/A20M.These requirements out-line the testing and retesting methods and procedures,permit-ted variations in dimensions,and mass,quality and repair ofdefects,marking,loading,and ordering information.3.2 Inadditiontothebasicrequirementsofthisspecification,certain supplementary requirements are availablewhen additional control,testing,or examination is required tomeet end use requirements.The purchaser is referred to thelisted supplementary requirements in this specification and tothe detailed requirements in Specification A20/A20M.1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.11 on Steel Plates for Boilers and Pressure Vessels.Current edition approved May 1,2016.Published May 2016.Originallyapproved in 1965.Last previous edition approved in 2014 as A533/A533M 09(2014).DOI:10.1520/A0533_A0533M-16.2For ASME Boiler and Pressure Vessel Code applications,see related Specifi-cation SA-533/SA-533M in Section II of that Code.3For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.3 If the requirements of this specification are in conflictwith the requirements of Specification A20/A20M,the require-ments of this specification shall prevail.4.Manufacture4.1 Steelmaking PracticeThe steel shall be killed andshall conform to the fine austenitic grain requirement ofSpecification A20/A20M.5.Heat Treatment5.1 All plates shall be heat treated by heating to a suitabletemperature within the range from 1550 to 1800F 845 to980C,holding for a sufficient time to obtain uniform tem-perature throughout the plate thickness and th
